SULKY-HARROW.

SPECIPICATIQN forming part of Letters Patent No. 372,357, dated November 1, 18 87.

I Application filed March 5, 1887. Serial No. 229,761. (No model.)

To aZZ whom it may concern.-

Be it known that we, NATHANIEL H. BEN- TON and HERBERT L. GODDING, citizens of the United States, residing at Madison, in the county of Dane and State of Wisconsin, have and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Our invention relates to harrows, and has for its object the production of a complete and eflicient sulky-harrow, which shall be capable of such changes as will enable us to use two or more horses abreast, as may be desired, by closing or spreading a double pole, and which shall possess means for accurately adjusting and securely fixing the depth of the harrow in the ground. In addition to these two leading objects, many minor but useful novel constructions of parts and improved results are attained, some of which may be mentioned, as follows; the novel means for unitingthe double pole, the novel means for spreading or separating the same, the draft attachment, the means'for securing the lovers for controlling the ends of the barrow-frames, the means for uniting the harrow-frames, the novel position in which theharrow-frames are held, and the novel brace for the axle, and a novel form of holding means for the harrow-teeth, and means for adjusting the seat.

The invention herein set forth is an improvement upon an application for patent on the same character of invention which has recently been allowed to us.

The accompanying drawings illustrate what we consider the best means for carrying our invention into practice.

Figure 1 is a plan view of the harrow, showing the doubletongue united in front as used for two horses. Fig. 2 is a plan View of the tongue or pole spread as is done when three or four horses are used. Fig. 3 is a side elevation of the machine with one wheel removed. Fig. 4 is a rear elevation-of the axle. Fig. 5

is a plan view of one of the harrow-beams, showing the means for attaching the teeth.

Fig. 6 is a side elevation of Fig. 5. Fig. 7 is a side elevation of the adjusting means for the frame-levers. Fig. 8 is a detail showing a portion of said adjusting moans.

Similar letters of reference indicate corre sponding parts in all the figures where they occur.

A is the axle, and B the tongue or pole. The axle is braced in a peculiar manner, as will hereinafter be explained. The pole is composed of two parts, each of whichis marked B. Each of the said parts is secured to the axle by pivots b b, and is provided at its outer end with projecting plates 1) b, perforated as shown, through which perforations a hook upon the yoke is inserted, and the two parts of the pole are thusunited at the front end. Diagonal braces b b extend from member to member of the pole at about the hitching-point. The forward ends of these braces are movable, and are set farther up the pole to bring the front ends thereof together, or are set farther back upon the pole to spread the parts or mem bers of the pole and cause them to stand about parallel with each other, as shown in Fig. 2. When they are thus spread, a double yoke will be used,as shown in Fig. 2. A hook or hanger, b may be placed at the point of crossing of the two braces and extend down to sustain the doubletree. At a point just back of the said braces and beneath the pole members are attached braces or brackets B B, to which the front ends of the levers G O are pivoted. These levers extend back under the pole members, where they are provided with stirrups for the feet of the driver. Between the front and rear ends the said levers have the chains for rais ing and lowering the ends of the harrowframes, as will be more fully explained hereinafter. They also have pivoted to them the upright arms D D, which pass through plates d d on the rear portion of the pole members B B, and the said arms are provided with nitches or notches, which are engaged by the said plates, and a spring, d, on each plate preserves the connection between the said arms and the plates. This notch in each of the arms is at just theproper point to drop the barrow-frames to the depth ordinarily required in pulverizing the soil, and which may be termed the normal position. An eccentric lever, E, pivoted upon the said pole members with a spring, 0, to keep it in engagement with the rack ll, bears with its curved or eccentric end upon each of the lovers 0 and aids the arms D in sustaining the harrow-framesin the normal position when said lever E is properly set. In addition to this function the lever E can be and is used for making the adjustments required in raising and lowering the ends of the harrow'frames. It will be seen that the said lever E, by being turned into an inclined position forward or backward, will depress or raise the levers O, and by the engagement with thcrack IE will securely hold them in the said depressed or elevated position. This is illustrated in Fig. 7, where the rear end of the levers G is elevated, which elevation will let the burrow run deeper.

It will be understood that the arms D are preferably made with the single notch to keep them at the normal position only; but they may have notches at different heights to help to hold the barrow-frames in any adjustment. It will also be noticed that the weight of the barrow-frames can be raised by foot-pressure upon the levers O and the strain, upon lever E relieved.

Braces F F, extending from a point on the pole members in front of the axle to a point on the same in the rear of the axle, are dropped under the axle and tend to stiffen the parts.

A longitudinal brace, G, is applied to the axle for the purpose of giving it strength by having the ends of the two members or part of said brace G fastened over the ends of the axle on top, and bent under or down and engaged near or at the center of the axle by a transverse metal piece, g, which clamps the said blfICOlllClllbGlS and gives it great tension and adds great strength to the axle.

The seat (marked II) is supported on arms hi1, which converge at the scat end and are spread out at the forward end and engaged in any desired one of a series of holes in the projcctions or brackets h. The arms h it rest upon the axle between the seat and the front connection, and by adjusting the front ends of the arms to different heights in the brackets 71/ the seat can be raised or lowered, as may be desired.

I I are the barrow-frames united by means ofa rod, 1, which passes through cars 1 i on thecndsofthcbcamsofthcframe. 'lheframes I I are set at an oblique angle to each other and to the axle, so as to cause the beams of the frames to slope backward from the point of union on the center of themachine. This position of the frames gives them the same qualities as the square harrow when hitched to a corner thereof, or ofthe double-Aharrow, well known in farming. The frames are held in substantially a uniform position laterally by means of the guide device J, which was shown and claimed in our previous application above referred to, while they are permitted to swing in a line with the progression of the burrow by the same device.

A chain, 1", is attached near the outer end of each frame I, and after passing over rollers on the axle is attached to the foot-levcr O in substantially the same manner shown and described in the said application.

A chain, 1 attached to about the center of the bar or rod I, is passed up over the adjusting cam-lever I substantiallylike that in the previous application.

The draft devices (marked K) are attached by means of chains I; to the barrow-frames, and by chains is to the brackets B, and, as before stated, a hook or hanger, b may be employed to connect the said draft devices to the braces 12, the hook or hanger being particularly intended for use when the draft device is not in use to keep it off the ground.

Teeth L are applied to the frame I by means of a crimped and angularly-molded piece of metal, L, which rests against the beam and a through hook or clamp, l, for holding the tooth and plate L against the beam. The construction of the plate L is such as to give a slight elastic quality to the device, and thus more securely hold the teeth.

When three or four horses are used, a different evencr and yoke are used. The yoke for three or four horses is shown in Fig. 2, where provision is made for the attachment of three single yokes.

Having thus described our invention, what we claim, and desire to secure by Letters Pat out oft'hc United States, is i t t i i 1. In a harrow or analogous device, a pair of pole members, I B, provided with the plates or parts I), permanently secured to the pole members, and having the projecting perforate portions, as described, said projecting perforate portions serving to hold the pole members together by the insertion of a ring or hook, and also serving to receive the ring or book of the yoke when the pole members are separated, said pole members being pivoted upon the axle, as set forth.

2. In a harrow or analogous device, the combination,with the pole members B B and means for uniting or separating them at the front ends, consisting of the plates I), secured to the said members, and having projecting portions with holes or perforations therein, said projecting portions b serving to hold the pole members together by the insertion of ring or hook, and also serving to receive the ring or hook of the yoke when the pole members are separated, of the braces b movable, as described, and applied to the pole members near the axle of the device.

3. The combination, with the barrow-frames pivotally connected, as described, chains connecting the ends thereof with foot-levers, of said foot-levers, and brackets set upon the under side of the pole members, to which brackets the fronts of the foot-levers are pivoted.

4:. In a harrow, the combination, with the adj ustablc frame, foot-lcvcrs for producing the adjustment, of the upright arms D, connected to the foot-levers and passing through plates provided with springs for holding the said arms at a normal elevation.

5. The combination, with the foot lever or levers for regulating the barrow-frames, of the eccentric lever E and means for setting it, as described. v

6. The combination, with the foot lever or levers, of the eccentric lever E, having its curved or eccentric end resting on the footlever, a rack, 11], for engaging said lever, and

a spring for preserving said engagement.

7. In a harrow, the combination, with the frame-beams, of the crimped and slightly-elastic plates L, the teeth L, and thethrongh bolt 15 or hook Z, all substantially as and for the purpose set forth. 1
